# Superclass for ActionController functional tests. Functional tests allow you to
-
# test a single controller action per test method. This should not be confused with
-
# integration tests (see ActionDispatch::IntegrationTest), which are more like
-
# "stories" that can involve multiple controllers and multiple actions (i.e. multiple
-
# different HTTP requests).
-
#
-
# == Basic example
-
#
-
# Functional tests are written as follows:
-
# 1. First, one uses the +get+, +post+, +patch+, +put+, +delete+ or +head+ method to simulate
-
# an HTTP request.
-
# 2. Then, one asserts whether the current state is as expected. "State" can be anything:
-
# the controller's HTTP response, the database contents, etc.
-
#
-
# For example:
-
#
-
# class BooksControllerTest < ActionController::TestCase
-
# def test_create
-
# # Simulate a POST response with the given HTTP parameters.
-
# post(:create, book: { title: "Love Hina" })
-
#
-
# # Assert that the controller tried to redirect us to
-
# # the created book's URI.
-
# assert_response :found
-
#
-
# # Assert that the controller really put the book in the database.
-
# assert_not_nil Book.find_by(title: "Love Hina")
-
# end
-
# end
-
#
-
# You can also send a real document in the simulated HTTP request.
-
#
-
# def test_create
-
# json = {book: { title: "Love Hina" }}.to_json
-
# post :create, json
-
# end
-
#
-
# == Special instance variables
-
#
-
# ActionController::TestCase will also automatically provide the following instance
-
# variables for use in the tests:
-
#
-
# <b>@controller</b>::
-
# The controller instance that will be tested.
-
# <b>@request</b>::
-
# An ActionController::TestRequest, representing the current HTTP
-
# request. You can modify this object before sending the HTTP request. For example,
-
# you might want to set some session properties before sending a GET request.
-
# <b>@response</b>::
-
# An ActionController::TestResponse object, representing the response
-
# of the last HTTP response. In the above example, <tt>@response</tt> becomes valid
-
# after calling +post+. If the various assert methods are not sufficient, then you
-
# may use this object to inspect the HTTP response in detail.
-
#
-
# (Earlier versions of \Rails required each functional test to subclass
-
# Test::Unit::TestCase and define @controller, @request, @response in +setup+.)
-
#
-
# == Controller is automatically inferred
-
#
-
# ActionController::TestCase will automatically infer the controller under test
-
# from the test class name. If the controller cannot be inferred from the test
-
# class name, you can explicitly set it with +tests+.
-
#
-
# class SpecialEdgeCaseWidgetsControllerTest < ActionController::TestCase
-
# tests WidgetController
-
# end
-
#
-
# == \Testing controller internals
-
#
-
# In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions
-
# can be used against. These collections are:
-
#
-
# * assigns: Instance variables assigned in the action that are available for the view.
-
# * session: Objects being saved in the session.
-
# * flash: The flash objects currently in the session.
-
# * cookies: \Cookies being sent to the user on this request.
-
#
-
# These collections can be used just like any other hash:
-
#
-
# assert_not_nil assigns(:person) # makes sure that a @person instance variable was set
-
# assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave"
-
# assert flash.empty? # makes sure that there's nothing in the flash
-
#
-
# For historic reasons, the assigns hash uses string-based keys. So <tt>assigns[:person]</tt> won't work, but <tt>assigns["person"]</tt> will. To
-
# appease our yearning for symbols, though, an alternative accessor has been devised using a method call instead of index referencing.
-
# So <tt>assigns(:person)</tt> will work just like <tt>assigns["person"]</tt>, but again, <tt>assigns[:person]</tt> will not work.
-
#
-
# On top of the collections, you have the complete url that a given action redirected to available in <tt>redirect_to_url</tt>.
-
#
-
# For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another
-
# action call which can then be asserted against.
-
#
-
# == Manipulating session and cookie variables
-
#
-
# Sometimes you need to set up the session and cookie variables for a test.
-
# To do this just assign a value to the session or cookie collection:
-
#
-
# session[:key] = "value"
-
# cookies[:key] = "value"
-
#
-
# To clear the cookies for a test just clear the cookie collection:
-
#
-
# cookies.clear
-
#
-
# == \Testing named routes
-
#
-
# If you're using named routes, they can be easily tested using the original named routes' methods straight in the test case.
-
#
-
# assert_redirected_to page_url(title: 'foo')

Support for this option in the `process` method (and the related

be removed in the next version without replacement.
-
-
Functional tests are essentially unit tests for controllers and

they should not require knowledge to how the application's routes

are configured. Instead, you should explicitly pass the appropiate

-
Previously the engines guide also contained an incorrect example

that recommended using this option to test an engine's controllers

within the dummy application. That recommendation was incorrect

and has since been corrected. Instead, you should override the

`@routes` variable in the test case with `Foo::Engine.routes`. See

the updated engines guide for details.

# Asserts that the routing of the given +path+ was handled correctly and that the parsed options (given in the +expected_options+ hash)
-
# match +path+. Basically, it asserts that \Rails recognizes the route given by +expected_options+.
-
#
-
# Pass a hash in the second argument (+path+) to specify the request method. This is useful for routes
-
# requiring a specific HTTP method. The hash should contain a :path with the incoming request path
-
# and a :method containing the required HTTP verb.
-
#
-
# # assert that POSTing to /items will call the create action on ItemsController
-
# assert_recognizes({controller: 'items', action: 'create'}, {path: 'items', method: :post})
-
#
-
# You can also pass in +extras+ with a hash containing URL parameters that would normally be in the query string. This can be used
-
# to assert that values in the query string string will end up in the params hash correctly. To test query strings you must use the
-
# extras argument, appending the query string on the path directly will not work. For example:
-
#
-
# # assert that a path of '/items/list/1?view=print' returns the correct options
-
# assert_recognizes({controller: 'items', action: 'list', id: '1', view: 'print'}, 'items/list/1', { view: "print" })

# The +message+ parameter allows you to pass in an error message that is displayed upon failure.

# # Check the default route (i.e., the index action)
-
# assert_recognizes({controller: 'items', action: 'index'}, 'items')

# CollectionAssociation is an abstract class that provides common stuff to

# CollectionAssociation:
-
# HasManyAssociation => has_many

# CollectionAssociation class provides common methods to the collections

# defined by +has_and_belongs_to_many+, +has_many+ or +has_many+ with
-
# +:through association+ option.
-
#
-
# You need to be careful with assumptions regarding the target: The proxy
-
# does not fetch records from the database until it needs them, but new
-
# ones created with +build+ are added to the target. So, the target may be
-
# non-empty and still lack children waiting to be read from the database.
-
# If you look directly to the database you cannot assume that's the entire
-
# collection because new records may have been added to the target, etc.
-
#
-
# If you need to work on all current children, new and existing records,
-
# +load_target+ and the +loaded+ flag are your friends.

# A JoinPart represents a part of a JoinDependency. It is inherited

# everything else is being joined onto. A JoinAssociation represents an association which
-
# is joining to the base. A JoinAssociation may result in more than one actual join
-
# operations (for example a has_and_belongs_to_many JoinAssociation would result in
-
# two; one for the join table and one for the target table).

# Implements the details of eager loading of Active Record associations.
-
#
-
# Suppose that you have the following two Active Record models:
-
#
-
# class Author < ActiveRecord::Base
-
# # columns: name, age
-
# has_many :books
-
# end
-
#
-
# class Book < ActiveRecord::Base
-
# # columns: title, sales
-
# end
-
#
-
# When you load an author with all associated books Active Record will make
-
# multiple queries like this:
-
#
-
# Author.includes(:books).where(:name => ['bell hooks', 'Homer').to_a
-
#
-
# => SELECT `authors`.* FROM `authors` WHERE `name` IN ('bell hooks', 'Homer')
-
# => SELECT `books`.* FROM `books` WHERE `author_id` IN (2, 5)
-
#
-
# Active Record saves the ids of the records from the first query to use in
-
# the second. Depending on the number of associations involved there can be
-
# arbitrarily many SQL queries made.
-
#
-
# However, if there is a WHERE clause that spans across tables Active
-
# Record will fall back to a slightly more resource-intensive single query:
-
#
-
# Author.includes(:books).where(books: {title: 'Illiad'}).to_a
-
# => SELECT `authors`.`id` AS t0_r0, `authors`.`name` AS t0_r1, `authors`.`age` AS t0_r2,
-
# `books`.`id` AS t1_r0, `books`.`title` AS t1_r1, `books`.`sales` AS t1_r2
-
# FROM `authors`
-
# LEFT OUTER JOIN `books` ON `authors`.`id` = `books`.`author_id`
-
# WHERE `books`.`title` = 'Illiad'
-
#
-
# This could result in many rows that contain redundant data and it performs poorly at scale
-
# and is therefore only used when necessary.

# Eager loads the named associations for the given Active Record record(s).
-
#
-
# In this description, 'association name' shall refer to the name passed
-
# to an association creation method. For example, a model that specifies
-
# <tt>belongs_to :author</tt>, <tt>has_many :buyers</tt> has association
-
# names +:author+ and +:buyers+.
-
#
-
# == Parameters
-
# +records+ is an array of ActiveRecord::Base. This array needs not be flat,
-
# i.e. +records+ itself may also contain arrays of records. In any case,
-
# +preload_associations+ will preload the all associations records by
-
# flattening +records+.
-
#
-
# +associations+ specifies one or more associations that you want to
-
# preload. It may be:
-
# - a Symbol or a String which specifies a single association name. For
-
# example, specifying +:books+ allows this method to preload all books
-
# for an Author.
-
# - an Array which specifies multiple association names. This array
-
# is processed recursively. For example, specifying <tt>[:avatar, :books]</tt>
-
# allows this method to preload an author's avatar as well as all of his
-
# books.
-
# - a Hash which specifies multiple association names, as well as
-
# association names for the to-be-preloaded association objects. For
-
# example, specifying <tt>{ author: :avatar }</tt> will preload a
-
# book's author, as well as that author's avatar.
-
#
-
# +:associations+ has the same format as the +:include+ option for
-
# <tt>ActiveRecord::Base.find</tt>. So +associations+ could look like this:
-
#
-
# :books
-
# [ :books, :author ]
-
# { author: :avatar }
-
# [ :books, { author: :avatar } ]

# \Fixtures are a way of organizing data that you want to test against; in short, sample data.
-
#
-
# They are stored in YAML files, one file per model, which are placed in the directory
-
# appointed by <tt>ActiveSupport::TestCase.fixture_path=(path)</tt> (this is automatically
-
# configured for Rails, so you can just put your files in <tt><your-rails-app>/test/fixtures/</tt>).
-
# The fixture file ends with the +.yml+ file extension, for example:
-
# <tt><your-rails-app>/test/fixtures/web_sites.yml</tt>).
-
#
-
# The format of a fixture file looks like this:
-
#
-
# rubyonrails:
-
# id: 1
-
# name: Ruby on Rails
-
# url: http://www.rubyonrails.org
-
#
-
# google:
-
# id: 2
-
# name: Google
-
# url: http://www.google.com
-
#
-
# This fixture file includes two fixtures. Each YAML fixture (ie. record) is given a name and
-
# is followed by an indented list of key/value pairs in the "key: value" format. Records are
-
# separated by a blank line for your viewing pleasure.
-
#
-
# Note: Fixtures are unordered. If you want ordered fixtures, use the omap YAML type.
-
# See http://yaml.org/type/omap.html
-
# for the specification. You will need ordered fixtures when you have foreign key constraints
-
# on keys in the same table. This is commonly needed for tree structures. Example:
-
#
-
# --- !omap
-
# - parent:
-
# id: 1
-
# parent_id: NULL
-
# title: Parent
-
# - child:
-
# id: 2
-
# parent_id: 1
-
# title: Child
-
#
-
# = Using Fixtures in Test Cases
-
#
-
# Since fixtures are a testing construct, we use them in our unit and functional tests. There
-
# are two ways to use the fixtures, but first let's take a look at a sample unit test:
-
#
-
# require 'test_helper'
-
#
-
# class WebSiteTest < ActiveSupport::TestCase
-
# test "web_site_count" do
-
# assert_equal 2, WebSite.count
-
# end
-
# end
-
#
-
# By default, +test_helper.rb+ will load all of your fixtures into your test
-
# database, so this test will succeed.
-
#
-
# The testing environment will automatically load the all fixtures into the database before each
-
# test. To ensure consistent data, the environment deletes the fixtures before running the load.
-
#
-
# In addition to being available in the database, the fixture's data may also be accessed by
-
# using a special dynamic method, which has the same name as the model, and accepts the
-
# name of the fixture to instantiate:
-
#
-
# test "find" do
-
# assert_equal "Ruby on Rails", web_sites(:rubyonrails).name
-
# end
-
#
-
# Alternatively, you may enable auto-instantiation of the fixture data. For instance, take the
-
# following tests:
-
#
-
# test "find_alt_method_1" do
-
# assert_equal "Ruby on Rails", @web_sites['rubyonrails']['name']
-
# end
-
#
-
# test "find_alt_method_2" do
-
# assert_equal "Ruby on Rails", @rubyonrails.name
-
# end
-
#
-
# In order to use these methods to access fixtured data within your testcases, you must specify one of the
-
# following in your <tt>ActiveSupport::TestCase</tt>-derived class:
-
#
-
# - to fully enable instantiated fixtures (enable alternate methods #1 and #2 above)
-
# self.use_instantiated_fixtures = true
-
#
-
# - create only the hash for the fixtures, do not 'find' each instance (enable alternate method #1 only)
-
# self.use_instantiated_fixtures = :no_instances
-
#
-
# Using either of these alternate methods incurs a performance hit, as the fixtured data must be fully
-
# traversed in the database to create the fixture hash and/or instance variables. This is expensive for
-
# large sets of fixtured data.
-
#
-
# = Dynamic fixtures with ERB
-
#
-
# Some times you don't care about the content of the fixtures as much as you care about the volume.
-
# In these cases, you can mix ERB in with your YAML fixtures to create a bunch of fixtures for load
-
# testing, like:
-
#
-
# <% 1.upto(1000) do |i| %>
-
# fix_<%= i %>:
-
# id: <%= i %>
-
# name: guy_<%= 1 %>
-
# <% end %>
-
#
-
# This will create 1000 very simple fixtures.
-
#
-
# Using ERB, you can also inject dynamic values into your fixtures with inserts like
-
# <tt><%= Date.today.strftime("%Y-%m-%d") %></tt>.
-
# This is however a feature to be used with some caution. The point of fixtures are that they're
-
# stable units of predictable sample data. If you feel that you need to inject dynamic values, then
-
# perhaps you should reexamine whether your application is properly testable. Hence, dynamic values
-
# in fixtures are to be considered a code smell.
-
#
-
# Helper methods defined in a fixture will not be available in other fixtures, to prevent against
-
# unwanted inter-test dependencies. Methods used by multiple fixtures should be defined in a module
-
# that is included in <tt>ActiveRecord::FixtureSet.context_class</tt>.
-
#
-
# - define a helper method in `test_helper.rb`
-
# module FixtureFileHelpers
-
# def file_sha(path)
-
# Digest::SHA2.hexdigest(File.read(Rails.root.join('test/fixtures', path)))
-
# end
-
# end
-
# ActiveRecord::FixtureSet.context_class.send :include, FixtureFileHelpers
-
#
-
# - use the helper method in a fixture
-
# photo:
-
# name: kitten.png
-
# sha: <%= file_sha 'files/kitten.png' %>
-
#
-
# = Transactional Fixtures
-
#
-
# Test cases can use begin+rollback to isolate their changes to the database instead of having to
-
# delete+insert for every test case.
-
#
-
# class FooTest < ActiveSupport::TestCase
-
# self.use_transactional_fixtures = true
-
#
-
# test "godzilla" do
-
# assert !Foo.all.empty?
-
# Foo.destroy_all
-
# assert Foo.all.empty?
-
# end
-
#
-
# test "godzilla aftermath" do
-
# assert !Foo.all.empty?
-
# end
-
# end
-
#
-
# If you preload your test database with all fixture data (probably in the rake task) and use
-
# transactional fixtures, then you may omit all fixtures declarations in your test cases since
-
# all the data's already there and every case rolls back its changes.
-
#
-
# In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to
-
# true. This will provide access to fixture data for every table that has been loaded through
-
# fixtures (depending on the value of +use_instantiated_fixtures+).
-
#
-
# When *not* to use transactional fixtures:
-
#
-
# 1. You're testing whether a transaction works correctly. Nested transactions don't commit until
-
# all parent transactions commit, particularly, the fixtures transaction which is begun in setup
-
# and rolled back in teardown. Thus, you won't be able to verify
-
# the results of your transaction until Active Record supports nested transactions or savepoints (in progress).
-
# 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM.
-
# Use InnoDB, MaxDB, or NDB instead.
-
#
-
# = Advanced Fixtures
-
#
-
# Fixtures that don't specify an ID get some extra features:
-
#
-
# * Stable, autogenerated IDs
-
# * Label references for associations (belongs_to, has_one, has_many)
-
# * HABTM associations as inline lists
-
#
-
# There are some more advanced features available even if the id is specified:
-
#
-
# * Autofilled timestamp columns
-
# * Fixture label interpolation
-
# * Support for YAML defaults
-
#
-
# == Stable, Autogenerated IDs
-
#
-
# Here, have a monkey fixture:
-
#
-
# george:
-
# id: 1
-
# name: George the Monkey
-
#
-
# reginald:
-
# id: 2
-
# name: Reginald the Pirate
-
#
-
# Each of these fixtures has two unique identifiers: one for the database
-
# and one for the humans. Why don't we generate the primary key instead?
-
# Hashing each fixture's label yields a consistent ID:
-
#
-
# george: # generated id: 503576764
-
# name: George the Monkey
-
#
-
# reginald: # generated id: 324201669
-
# name: Reginald the Pirate
-
#
-
# Active Record looks at the fixture's model class, discovers the correct
-
# primary key, and generates it right before inserting the fixture
-
# into the database.
-
#
-
# The generated ID for a given label is constant, so we can discover
-
# any fixture's ID without loading anything, as long as we know the label.
-
#
-
# == Label references for associations (belongs_to, has_one, has_many)
-
#
-
# Specifying foreign keys in fixtures can be very fragile, not to
-
# mention difficult to read. Since Active Record can figure out the ID of
-
# any fixture from its label, you can specify FK's by label instead of ID.
-
#
-
# === belongs_to
-
#
-
# Let's break out some more monkeys and pirates.
-
#
-
# ### in pirates.yml
-
#
-
# reginald:
-
# id: 1
-
# name: Reginald the Pirate
-
# monkey_id: 1
-
#
-
# ### in monkeys.yml
-
#
-
# george:
-
# id: 1
-
# name: George the Monkey
-
# pirate_id: 1
-
#
-
# Add a few more monkeys and pirates and break this into multiple files,
-
# and it gets pretty hard to keep track of what's going on. Let's
-
# use labels instead of IDs:
-
#
-
# ### in pirates.yml
-
#
-
# reginald:
-
# name: Reginald the Pirate
-
# monkey: george
-
#
-
# ### in monkeys.yml
-
#
-
# george:
-
# name: George the Monkey
-
# pirate: reginald
-
#
-
# Pow! All is made clear. Active Record reflects on the fixture's model class,
-
# finds all the +belongs_to+ associations, and allows you to specify
-
# a target *label* for the *association* (monkey: george) rather than
-
# a target *id* for the *FK* (<tt>monkey_id: 1</tt>).
-
#
-
# ==== Polymorphic belongs_to
-
#
-
# Supporting polymorphic relationships is a little bit more complicated, since
-
# Active Record needs to know what type your association is pointing at. Something
-
# like this should look familiar:
-
#
-
# ### in fruit.rb
-
#
-
# belongs_to :eater, polymorphic: true
-
#
-
# ### in fruits.yml
-
#
-
# apple:
-
# id: 1
-
# name: apple
-
# eater_id: 1
-
# eater_type: Monkey
-
#
-
# Can we do better? You bet!
-
#
-
# apple:
-
# eater: george (Monkey)
-
#
-
# Just provide the polymorphic target type and Active Record will take care of the rest.
-
#
-
# === has_and_belongs_to_many
-
#
-
# Time to give our monkey some fruit.
-
#
-
# ### in monkeys.yml
-
#
-
# george:
-
# id: 1
-
# name: George the Monkey
-
#
-
# ### in fruits.yml
-
#
-
# apple:
-
# id: 1
-
# name: apple
-
#
-
# orange:
-
# id: 2
-
# name: orange
-
#
-
# grape:
-
# id: 3
-
# name: grape
-
#
-
# ### in fruits_monkeys.yml
-
#
-
# apple_george:
-
# fruit_id: 1
-
# monkey_id: 1
-
#
-
# orange_george:
-
# fruit_id: 2
-
# monkey_id: 1
-
#
-
# grape_george:
-
# fruit_id: 3
-
# monkey_id: 1
-
#
-
# Let's make the HABTM fixture go away.
-
#
-
# ### in monkeys.yml
-
#
-
# george:
-
# id: 1
-
# name: George the Monkey
-
# fruits: apple, orange, grape
-
#
-
# ### in fruits.yml
-
#
-
# apple:
-
# name: apple
-
#
-
# orange:
-
# name: orange
-
#
-
# grape:
-
# name: grape
-
#
-
# Zap! No more fruits_monkeys.yml file. We've specified the list of fruits
-
# on George's fixture, but we could've just as easily specified a list
-
# of monkeys on each fruit. As with +belongs_to+, Active Record reflects on
-
# the fixture's model class and discovers the +has_and_belongs_to_many+
-
# associations.
-
#
-
# == Autofilled Timestamp Columns
-
#
-
# If your table/model specifies any of Active Record's
-
# standard timestamp columns (+created_at+, +created_on+, +updated_at+, +updated_on+),
-
# they will automatically be set to <tt>Time.now</tt>.
-
#
-
# If you've set specific values, they'll be left alone.
-
#
-
# == Fixture label interpolation
-
#
-
# The label of the current fixture is always available as a column value:
-
#
-
# geeksomnia:
-
# name: Geeksomnia's Account
-
# subdomain: $LABEL
-
# email: $LABEL@email.com
-
#
-
# Also, sometimes (like when porting older join table fixtures) you'll need
-
# to be able to get a hold of the identifier for a given label. ERB
-
# to the rescue:
-
#
-
# george_reginald:
-
# monkey_id: <%= ActiveRecord::FixtureSet.identify(:reginald) %>
-
# pirate_id: <%= ActiveRecord::FixtureSet.identify(:george) %>
-
#
-
# == Support for YAML defaults
-
#
-
# You can set and reuse defaults in your fixtures YAML file.
-
# This is the same technique used in the +database.yml+ file to specify
-
# defaults:
-
#
-
# DEFAULTS: &DEFAULTS
-
# created_on: <%= 3.weeks.ago.to_s(:db) %>
-
#
-
# first:
-
# name: Smurf
-
# <<: *DEFAULTS
-
#
-
# second:
-
# name: Fraggle
-
# <<: *DEFAULTS
-
#
-
# Any fixture labeled "DEFAULTS" is safely ignored.

#
-
# Renders activity to the given ActionView context with included
-
# AV::Helpers::RenderingHelper (most commonly just ActionView::Base)
-
#
-
# The *preferred* *way* of rendering activities is
-
# to provide a template specifying how the rendering should be happening.
-
# However, one may choose using _I18n_ based approach when developing
-
# an application that supports plenty of languages.
-
#
-
# If partial view exists that matches the *key* attribute
-
# renders that partial with local variables set to contain both
-
# Activity and activity_parameters (hash with indifferent access)
-
#
-
# Otherwise, it outputs the I18n translation to the context
-
# @example Render a list of all activities from a view (erb)
-
# <ul>
-
# <% for activity in PublicActivity::Activity.all %>
-
# <li><%= render_activity(activity) %></li>
-
# <% end %>
-
# </ul>
-
#
-
# = Layouts
-
# You can supply a layout that will be used for activity partials
-
# with :layout param.
-
# Keep in mind that layouts for partials are also partials.
-
# @example Supply a layout
-
# # in views:
-
# # All examples look for a layout in app/views/layouts/_activity.erb
-
# render_activity @activity, :layout => "activity"
-
# render_activity @activity, :layout => "layouts/activity"
-
# render_activity @activity, :layout => :activity
-
#
-
# # app/views/layouts/_activity.erb
-
# <p><%= a.created_at %></p>
-
# <%= yield %>
-
#
-
# == Custom Layout Location
-
# You can customize the layout directory by supplying :layout_root
-
# or by using an absolute path.
-
#
-
# @example Declare custom layout location
-
#
-
# # Both examples look for a layout in "app/views/custom/_layout.erb"
-
#
-
# render_activity @activity, :layout_root => "custom"
-
# render_activity @activity, :layout => "/custom/layout"
-
#
-
# = Creating a template
-
# To use templates for formatting how the activity should render,
-
# create a template based on activity key, for example:
-
#
-
# Given a key _activity.article.create_, create directory tree
-
# _app/views/public_activity/article/_ and create the _create_ partial there
-
#
-
# Note that if a key consists of more than three parts splitted by commas, your
-
# directory structure will have to be deeper, for example:
-
# activity.article.comments.destroy => app/views/public_activity/articles/comments/_destroy.html.erb
-
#
-
# == Custom Directory
-
# You can override the default `public_directory` template root with the :root parameter
-
#
-
# @example Custom template root
-
# # look for templates inside of /app/views/custom instead of /app/views/public_directory
-
# render_activity @activity, :root => "custom"
-
#
-
# == Variables in templates
-
# From within a template there are two variables at your disposal:
-
# * activity (aliased as *a* for a shortcut)
-
# * params (aliased as *p*) [converted into a HashWithIndifferentAccess]
-
#
-
# @example Template for key: _activity.article.create_ (erb)
-
# <p>
-
# Article <strong><%= p[:name] %></strong>
-
# was written by <em><%= p["author"] %></em>
-
# <%= distance_of_time_in_words_to_now(a.created_at) %>
-
# </p>

# Module with basic +tracked+ method that enables tracking models.
-
1
module ClassMethods
-
# Adds required callbacks for creating and updating
-
# tracked models and adds +activities+ relation for listing
-
# associated activities.
-
#
-
# == Parameters:
-
# [:owner]
-
# Specify the owner of the {Activity} (person responsible for the action).
-
# It can be a Proc, Symbol or an ActiveRecord object:
-
# == Examples:
-
#
-
# tracked :owner => :author
-
# tracked :owner => proc {|o| o.author}
-
#
-
# Keep in mind that owner relation is polymorphic, so you can't just
-
# provide id number of the owner object.
-
# [:recipient]
-
# Specify the recipient of the {Activity}
-
# It can be a Proc, Symbol, or an ActiveRecord object
-
# == Examples:
-
#
-
# tracked :recipient => :author
-
# tracked :recipient => proc {|o| o.author}
-
#
-
# Keep in mind that recipient relation is polymorphic, so you can't just
-
# provide id number of the owner object.
-
# [:params]
-
# Accepts a Hash with custom parameters you want to pass to i18n.translate
-
# method. It is later used in {Renderable#text} method.
-
# == Example:
-
# class Article < ActiveRecord::Base
-
# include PublicActivity::Model
-
# tracked :params => {
-
# :title => :title,
-
# :author_name => "Michael",
-
# :category_name => proc {|controller, model_instance| model_instance.category.name},
-
# :summary => proc {|controller, model_instance| truncate(model.text, :length => 30)}
-
# }
-
# end
-
#
-
# Values in the :params hash can either be an *exact* *value*, a *Proc/Lambda* executed before saving the activity or a *Symbol*
-
# which is a an attribute or a method name executed on the tracked model's instance.
-
#
-
# Everything specified here has a lower priority than parameters
-
# specified directly in {#activity} method.
-
# So treat it as a place where you provide 'default' values or where you
-
# specify what data should be gathered for every activity.
-
# For more dynamic settings refer to {Activity} model documentation.
-
# [:skip_defaults]
-
# Disables recording of activities on create/update/destroy leaving that to programmer's choice. Check {PublicActivity::Common#create_activity}
-
# for a guide on how to manually record activities.
-
# [:only]
-
# Accepts a symbol or an array of symbols, of which any combination of the three is accepted:
-
# * _:create_
-
# * _:update_
-
# * _:destroy_
-
# Selecting one or more of these will make PublicActivity create activities
-
# automatically for the tracked model on selected actions.
-
#
-
# Resulting activities will have have keys assigned to, respectively:
-
# * _article.create_
-
# * _article.update_
-
# * _article.destroy_
-
# Since only three options are valid,
-
# see _:except_ option for a shorter version
-
# [:except]
-
# Accepts a symbol or an array of symbols with values like in _:only_, above.
-
# Values provided will be subtracted from all default actions:
-
# (create, update, destroy).
-
#
-
# So, passing _create_ would track and automatically create
-
# activities on _update_ and _destroy_ actions,
-
# but not on the _create_ action.
-
# [:on]
-
# Accepts a Hash with key being the *action* on which to execute *value* (proc)
-
# Currently supported only for CRUD actions which are enabled in _:only_
-
# or _:except_ options on this method.
-
#
-
# Key-value pairs in this option define callbacks that can decide
-
# whether to create an activity or not. Procs have two attributes for
-
# use: _model_ and _controller_. If the proc returns true, the activity
-
# will be created, if not, then activity will not be saved.
-
#
-
# == Example:
-
# # app/models/article.rb
-
# tracked :on => {:update => proc {|model, controller| model.published? }}
-
#
-
# In the example above, given a model Article with boolean column _published_.
-
# The activities with key _article.update_ will only be created
-
# if the published status is set to true on that article.
-
# @param opts [Hash] options
-
# @return [nil] options

-
## The environment is required to include these variables
-
## (adopted from PEP333), except when they'd be empty, but see
-
## below.
-
-
## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
-
## "GET" or "POST". This cannot ever
-
## be an empty string, and so is
-
## always required.
-
-
## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
-
## URL's "path" that corresponds to the
-
## application object, so that the
-
## application knows its virtual
-
## "location". This may be an empty
-
## string, if the application corresponds
-
## to the "root" of the server.
-
-
## <tt>PATH_INFO</tt>:: The remainder of the request URL's
-
## "path", designating the virtual
-
## "location" of the request's target
-
## within the application. This may be an
-
## empty string, if the request URL targets
-
## the application root and does not have a
-
## trailing slash. This value may be
-
## percent-encoded when I originating from
-
## a URL.
-
-
## <tt>QUERY_STRING</tt>:: The portion of the request URL that
-
## follows the <tt>?</tt>, if any. May be
-
## empty, but is always required!
-
-
## <tt>SERVER_NAME</tt>, <tt>SERVER_PORT</tt>::
-
## When combined with <tt>SCRIPT_NAME</tt> and
-
## <tt>PATH_INFO</tt>, these variables can be
-
## used to complete the URL. Note, however,
-
## that <tt>HTTP_HOST</tt>, if present,
-
## should be used in preference to
-
## <tt>SERVER_NAME</tt> for reconstructing
-
## the request URL.
-
## <tt>SERVER_NAME</tt> and <tt>SERVER_PORT</tt>
-
## can never be empty strings, and so
-
## are always required.
-
-
## <tt>HTTP_</tt> Variables:: Variables corresponding to the
-
## client-supplied HTTP request
-
## headers (i.e., variables whose
-
## names begin with <tt>HTTP_</tt>). The
-
## presence or absence of these
-
## variables should correspond with
-
## the presence or absence of the
-
## appropriate HTTP header in the
-
## request. See
-
## <a href="https://tools.ietf.org/html/rfc3875#section-4.1.18">
-
## RFC3875 section 4.1.18</a> for
-
## specific behavior.
-
-
## In addition to this, the Rack environment must include these
-
## Rack-specific variables:
-
-
## <tt>rack.version</tt>:: The Array representing this version of Rack
-
## See Rack::VERSION, that corresponds to
-
## the version of this SPEC.
-
-
## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the
-
## request URL.
-
-
## <tt>rack.input</tt>:: See below, the input stream.
-
-
## <tt>rack.errors</tt>:: See below, the error stream.
-
-
## <tt>rack.multithread</tt>:: true if the application object may be
-
## simultaneously invoked by another thread
-
## in the same process, false otherwise.
-
-
## <tt>rack.multiprocess</tt>:: true if an equivalent application object
-
## may be simultaneously invoked by another
-
## process, false otherwise.
-
-
## <tt>rack.run_once</tt>:: true if the server expects
-
## (but does not guarantee!) that the
-
## application will only be invoked this one
-
## time during the life of its containing
-
## process. Normally, this will only be true
-
## for a server based on CGI
-
## (or something similar).
-
-
## <tt>rack.hijack?</tt>:: present and true if the server supports
-
## connection hijacking. See below, hijacking.
-
-
## <tt>rack.hijack</tt>:: an object responding to #call that must be
-
## called at least once before using
-
## rack.hijack_io.
-
## It is recommended #call return rack.hijack_io
-
## as well as setting it in env if necessary.
-
-
## <tt>rack.hijack_io</tt>:: if rack.hijack? is true, and rack.hijack
-
## has received #call, this will contain
-
## an object resembling an IO. See hijacking.
-
-
## Additional environment specifications have approved to
-
## standardized middleware APIs. None of these are required to
-
## be implemented by the server.
-
-
## <tt>rack.session</tt>:: A hash like interface for storing
-
## request session data.
-
## The store must implement:
-
if session = env['rack.session']
-
## store(key, value) (aliased as []=);
-
assert("session #{session.inspect} must respond to store and []=") {

-
assert("session #{session.inspect} must respond to clear") {
-

-
end
-
-
## <tt>rack.logger</tt>:: A common object interface for logging messages.
-
## The object must implement:
-
if logger = env['rack.logger']
-
## info(message, &block)
-
assert("logger #{logger.inspect} must respond to info") {

-
if bufsize = env['rack.multipart.buffer_size']
-
assert("rack.multipart.buffer_size must be an Integer > 0 if specified") {

-
-
## <tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind. This factory will be used to instantiate the tempfile for each multipart form file upload field, rather than the default class of Tempfile.

-
## Users are encouraged to utilize this API with a knowledge of their
-
## server choice, and servers may extend the functionality of
-
## hijack_io to provide additional features to users. The purpose of
-
## rack.hijack is for Rack to "get out of the way", as such, Rack only

## provides the minimum of specification and support.

## ==== Response (after headers)
-
## It is also possible to hijack a response after the status and headers
-
## have been sent.
-
1

-
-
# this check uses headers like a hash, but the spec only requires

# headers respond to #each
-

-
## <tt>rack.hijack</tt> to an object that responds to <tt>call</tt>
-
## accepting an argument that conforms to the <tt>rack.hijack_io</tt>
-
## protocol.
-
##
-
## After the headers have been sent, and this hijack callback has been
-
## called, the application is now responsible for the remaining lifecycle
-
## of the IO. The application is also responsible for maintaining HTTP
-
## semantics. Of specific note, in almost all cases in the current SPEC,
-
## applications will have wanted to specify the header Connection:close in
-
## HTTP/1.1, and not Connection:keep-alive, as there is no protocol for
-
## returning hijacked sockets to the web server. For that purpose, use the
-
## body streaming API instead (progressively yielding strings via each).
-
##
-
## Servers must ignore the <tt>body</tt> part of the response tuple when
-
## the <tt>rack.hijack</tt> response API is in use.
-
-
if env['rack.hijack?'] && headers['rack.hijack']

original_hijack.call HijackWrapper.new(io)

end
-
else

##
-
## The special response header <tt>rack.hijack</tt> must only be set
-
## if the request env has <tt>rack.hijack?</tt> <tt>true</tt>.
-
assert('rack.hijack header must not be present if server does not support hijacking') {
-
headers['rack.hijack'].nil?
-
}
-
end
-
end
-
## ==== Conventions
-
## * Middleware should not use hijack unless it is handling the whole
-
## response.
-
## * Middleware may wrap the IO object for the response pattern.
-
## * Middleware should not wrap the IO object for the request pattern. The
-
## request pattern is intended to provide the hijacker with "raw tcp".

-
# greater than this number.
-
# * <tt>:only</tt>: another hash consisting of the keys to use

# counted.
-
# * <tt>:content</tt>: the textual content of the node must match the
-
# given value. This will not match HTML tags in the body of a

-
# Conditions are matched using the following algorithm:

# RSpec::Expectations provides a simple, readable API to express
-
# the expected outcomes in a code example. To express an expected
-
# outcome, wrap an object or block in `expect`, call `to` or `to_not`
-
# (aliased as `not_to`) and pass it a matcher object:
-
#
-
# expect(order.total).to eq(Money.new(5.55, :USD))
-
# expect(list).to include(user)
-
# expect(message).not_to match(/foo/)
-
# expect { do_something }.to raise_error
-
#
-
# The last form (the block form) is needed to match against ruby constructs
-
# that are not objects, but can only be observed when executing a block
-
# of code. This includes raising errors, throwing symbols, yielding,
-
# and changing values.
-
#
-
# When `expect(...).to` is invoked with a matcher, it turns around
-
# and calls `matcher.matches?(<object wrapped by expect>)`. For example,
-
# in the expression:
-
#
-
# expect(order.total).to eq(Money.new(5.55, :USD))
-
#
-
# ...`eq(Money.new(5.55, :USD))` returns a matcher object, and it results
-
# in the equivalent of `eq.matches?(order.total)`. If `matches?` returns
-
# `true`, the expectation is met and execution continues. If `false`, then
-
# the spec fails with the message returned by `eq.failure_message`.
-
#
-
# Given the expression:
-
#
-
# expect(order.entries).not_to include(entry)
-
#
-

1
module RSpec
-
# RSpec::Matchers provides a number of useful matchers we use to define
-
# expectations. Any object that implements the [matcher protocol](Matchers/MatcherProtocol)
-
# can be used as a matcher.
-
#
-
# ## Predicates
-
#
-
# In addition to matchers that are defined explicitly, RSpec will create
-
# custom matchers on the fly for any arbitrary predicate, giving your specs a
-
# much more natural language feel.
-
#
-
# A Ruby predicate is a method that ends with a "?" and returns true or false.
-
# Common examples are `empty?`, `nil?`, and `instance_of?`.
-
#
-
# All you need to do is write `expect(..).to be_` followed by the predicate
-
# without the question mark, and RSpec will figure it out from there.
-
# For example:
-
#
-
# expect([]).to be_empty # => [].empty?() | passes
-
# expect([]).not_to be_empty # => [].empty?() | fails
-
#
-
# In addtion to prefixing the predicate matchers with "be_", you can also use "be_a_"
-
# and "be_an_", making your specs read much more naturally:
-
#
-
# expect("a string").to be_an_instance_of(String) # =>"a string".instance_of?(String) # passes
-
#
-
# expect(3).to be_a_kind_of(Fixnum) # => 3.kind_of?(Numeric) | passes
-
# expect(3).to be_a_kind_of(Numeric) # => 3.kind_of?(Numeric) | passes
-
# expect(3).to be_an_instance_of(Fixnum) # => 3.instance_of?(Fixnum) | passes
-
# expect(3).not_to be_an_instance_of(Numeric) # => 3.instance_of?(Numeric) | fails
-
#
-
# RSpec will also create custom matchers for predicates like `has_key?`. To
-
# use this feature, just state that the object should have_key(:key) and RSpec will
-
# call has_key?(:key) on the target. For example:
-
#
-
# expect(:a => "A").to have_key(:a)
-
# expect(:a => "A").to have_key(:b) # fails
-
#
-
# You can use this feature to invoke any predicate that begins with "has_", whether it is
-
# part of the Ruby libraries (like `Hash#has_key?`) or a method you wrote on your own class.
-
#
-
# Note that RSpec does not provide composable aliases for these dynamic predicate
-
# matchers. You can easily define your own aliases, though:
-
#
-
# RSpec::Matchers.alias_matcher :a_user_who_is_an_admin, :be_an_admin
-
# expect(user_list).to include(a_user_who_is_an_admin)
-
#
-
# ## Custom Matchers
-
#
-
# When you find that none of the stock matchers provide a natural feeling
-
# expectation, you can very easily write your own using RSpec's matcher DSL
-
# or writing one from scratch.
-
#
-
# ### Matcher DSL
-
#
-
# Imagine that you are writing a game in which players can be in various
-
# zones on a virtual board. To specify that bob should be in zone 4, you
-
# could say:
-
#
-
# expect(bob.current_zone).to eql(Zone.new("4"))
-
#
-
# But you might find it more expressive to say:
-
#
-
# expect(bob).to be_in_zone("4")
-
#
-
# and/or
-
#
-
# expect(bob).not_to be_in_zone("3")
-
#
-
# You can create such a matcher like so:
-
#
-
# RSpec::Matchers.define :be_in_zone do |zone|
-
# match do |player|
-
# player.in_zone?(zone)
-
# end
-
# end
-
#
-
# This will generate a <tt>be_in_zone</tt> method that returns a matcher
-
# with logical default messages for failures. You can override the failure
-
# messages and the generated description as follows:
-
#
-
# RSpec::Matchers.define :be_in_zone do |zone|
-
# match do |player|
-
# player.in_zone?(zone)
-
# end
-
#
-
# failure_message do |player|
-
# # generate and return the appropriate string.
-
# end
-
#
-
# failure_message_when_negated do |player|
-
# # generate and return the appropriate string.
-
# end
-
#
-
# description do
-
# # generate and return the appropriate string.
-
# end
-
# end
-
#
-
# Each of the message-generation methods has access to the block arguments
-
# passed to the <tt>create</tt> method (in this case, <tt>zone</tt>). The
-
# failure message methods (<tt>failure_message</tt> and
-
# <tt>failure_message_when_negated</tt>) are passed the actual value (the
-
# receiver of <tt>expect(..)</tt> or <tt>expect(..).not_to</tt>).
-
#
-
# ### Custom Matcher from scratch
-
#
-
# You could also write a custom matcher from scratch, as follows:
-
#
-
# class BeInZone
-
# def initialize(expected)
-
# @expected = expected
-
# end
-
#
-
# def matches?(target)
-

-
#
-
# def be_in_zone(expected)
-

#
-
# And then expose the method to your specs. This is normally done
-
# by including the method and the class in a module, which is then
-
# included in your spec:
-
#
-
# module CustomGameMatchers
-
# class BeInZone
-
# # ...
-
# end
-
#
-
# def be_in_zone(expected)
-
# # ...
-
# end
-
# end
-
#
-
# describe "Player behaviour" do
-
# include CustomGameMatchers
-
# # ...
-
# end
-
#
-
# or you can include in globally in a spec_helper.rb file <tt>require</tt>d
-
# from your spec file(s):
-
#
-
# RSpec::configure do |config|
-
# config.include(CustomGameMatchers)
-
# end
-
#
-
# ### Making custom matchers composable
-
#
-
# RSpec's built-in matchers are designed to be composed, in expressions like:
-
#
-
# expect(["barn", 2.45]).to contain_exactly(
-
# a_value_within(0.1).of(2.5),
-
# a_string_starting_with("bar")
-
# )
-
#
-
# Custom matchers can easily participate in composed matcher expressions like these.
-
# Include {RSpec::Matchers::Composable} in your custom matcher to make it support
-
# being composed (matchers defined using the DSL have this included automatically).
-
# Within your matcher's `matches?` method (or the `match` block, if using the DSL),
-
# use `values_match?(expected, actual)` rather than `expected == actual`.
-
# Under the covers, `values_match?` is able to match arbitrary
-
# nested data structures containing a mix of both matchers and non-matcher objects.
-
# It uses `===` and `==` to perform the matching, considering the values to
-
# match if either returns `true`. The `Composable` mixin also provides some helper
-
# methods for surfacing the matcher descriptions within your matcher's description
-
# or failure messages.
-
#
-
# RSpec's built-in matchers each have a number of aliases that rephrase the matcher
-
# from a verb phrase (such as `be_within`) to a noun phrase (such as `a_value_within`),
-
# which reads better when the matcher is passed as an argument in a composed matcher
-
# expressions, and also uses the noun-phrase wording in the matcher's `description`,
-
# for readable failure messages. You can alias your custom matchers in similar fashion
-
# using {RSpec::Matchers.alias_matcher}.
-

module Matchers
-
# @method expect
-
# Supports `expect(actual).to matcher` syntax by wrapping `actual` in an
-
# `ExpectationTarget`.
-
# @example
-
# expect(actual).to eq(expected)
-
# expect(actual).not_to eq(expected)
-
# @return [ExpectationTarget]
-
# @see ExpectationTarget#to
-
# @see ExpectationTarget#not_to

# Defines a matcher alias. The returned matcher's `description` will be overriden
-
# to reflect the phrasing of the new name, which will be used in failure messages
-
# when passed as an argument to another matcher in a composed matcher expression.
-
#
-
# @param new_name [Symbol] the new name for the matcher

# block is provided, a default override is used based on the old and new names.
-
#
-
# @example
-
# RSpec::Matchers.alias_matcher :a_list_that_sums_to, :sum_to
-
# sum_to(3).description # => "sum to 3"
-
# a_list_that_sums_to(3).description # => "a list that sums to 3"
-
#
-
# @example
-
# RSpec::Matchers.alias_matcher :a_list_sorted_by, :be_sorted_by do |description|
-
# description.sub("be sorted by", "a list sorted by")

# Once we started supporting composing matchers, the algorithm for this matcher got

-

-
#
-
# This should pass (because we can pair /fool/ with "fool" and /foo/ with "food"), but

# the original algorithm used by this matcher would pair the first elements it could
-
# (/foo/ with "fool"), which would leave /fool/ and "food" unmatched. When we have

# problem space:
-
#
-
# * Any items which match none of the items in the other list are immediately
-
# placed into the `unmatched_expected_indexes` or `unmatched_actual_indexes` array.

# The extra items and missing items in the matcher failure message are derived
-
# from these arrays.
-
# * Any items which reciprocally match only each other are paired up and not
-
# considered further.
-
#
-
# What's left is only the items which match multiple items from the other list
-
# (or vice versa). From here, it performs a brute-force depth-first search,
-
# looking for a solution which pairs all elements in both lists, or, barring that,
-
# that produces the fewest unmatched items.

-
-
specify { expect(object).to matcher }
-
-
or this:
-

it { is_expected.to matcher }

RSpec expects the matcher to have a #description method. You should either

add a String to the example this matcher is being used in, or give it a

description method. Then you won't have to suffer this lengthy warning again.

-
# @method receive
-
# Used to specify a message that you expect or allow an object
-
# to receive. The object returned by `receive` supports the same
-
# fluent interface that `should_receive` and `stub` have always
-
# supported, allowing you to constrain the arguments or number of
-
# times, and configure how the object should respond to the message.
-
#
-
# @example
-
# expect(obj).to receive(:hello).with("world").exactly(3).times
-
#
-
# @note If you disable the `:expect` syntax this method will be undefined.
-
-
# @method receive_messages
-
# Shorthand syntax used to setup message(s), and their return value(s),
-
# that you expect or allow an object to receive. The method takes a hash
-
# of messages and their respective return values. Unlike with `receive`,
-
# you cannot apply further customizations using a block or the fluent
-
# interface.
-
#
-
# @example
-
# allow(obj).to receive_messages(:speak => "Hello World")
-
# allow(obj).to receive_messages(:speak => "Hello", :meow => "Meow")

# @note If you disable the `:expect` syntax this method will be undefined.

-
#
-
# stubs/mocks a chain of messages on an object or test double.
-
#
-
# ## Warning:
-
#
-
# Chains can be arbitrarily long, which makes it quite painless to
-
# violate the Law of Demeter in violent ways, so you should consider any
-
# use of `receive_message_chain` a code smell. Even though not all code smells
-
# indicate real problems (think fluent interfaces), `receive_message_chain` still
-
# results in brittle examples. For example, if you write
-
# `allow(foo).to receive_message_chain(:bar, :baz => 37)` in a spec and then the
-
# implementation calls `foo.baz.bar`, the stub will not work.
-
#
-
# @example
-
# allow(double).to receive_message_chain("foo.bar") { :baz }
-
# allow(double).to receive_message_chain(:foo, :bar => :baz)
-
# allow(double).to receive_message_chain(:foo, :bar) { :baz }
-
#
-
# # Given any of ^^ these three forms ^^:
-
# double.foo.bar # => :baz

# allow(Article).to receive_message_chain("recent.published") { [Article.new] }

# @method unstub
-
# Removes a stub. On a double, the object will no longer respond to
-
# `message`. On a real object, the original method (if it exists) is
-
# restored.
-
#
-
# This is rarely used, but can be useful when a stub is set up during a
-
# shared `before` hook for the common case, but you want to replace it
-
# for a special case.

#

# @note This is only available when you have enabled the `should` syntax.

# @method stub_chain
-
# @overload stub_chain(method1, method2)

-
#
-
# Stubs a chain of methods.
-
#
-
# ## Warning:
-
#
-
# Chains can be arbitrarily long, which makes it quite painless to
-
# violate the Law of Demeter in violent ways, so you should consider any
-
# use of `stub_chain` a code smell. Even though not all code smells
-
# indicate real problems (think fluent interfaces), `stub_chain` still
-
# results in brittle examples. For example, if you write
-
# `foo.stub_chain(:bar, :baz => 37)` in a spec and then the
-
# implementation calls `foo.baz.bar`, the stub will not work.
-
#
-
# @example
-
# double.stub_chain("foo.bar") { :baz }
-
# double.stub_chain(:foo, :bar => :baz)
-
# double.stub_chain(:foo, :bar) { :baz }
-
#
-
# # Given any of ^^ these three forms ^^:
-
# double.foo.bar # => :baz
-
#
-
# # Common use in Rails/ActiveRecord:
-
# Article.stub_chain("recent.published") { [Article.new] }

#
-
# @note This is only available when you have enabled the `should` syntax.

# @see RSpec::Mocks::ExampleMethods#receive_message_chain

# @method as_null_object
-
# Tells the object to respond to all messages. If specific stub values

-
# @note This is only available when you have enabled the `should` syntax.

# @method any_instance
-
# Used to set stubs and message expectations on any instance of a given
-
# class. Returns a [Recorder](Recorder), which records messages like
-
# `stub` and `should_receive` for later playback on instances of the
-
# class.
-
#
-
# @example
-
# Car.any_instance.should_receive(:go)
-
# race = Race.new
-
# race.cars << Car.new
-
# race.go # assuming this delegates to all of its cars
-
# # this example would pass
-
#
-
# Account.any_instance.stub(:balance) { Money.new(:USD, 25) }
-
# Account.new.balance # => Money.new(:USD, 25))
-
#

# the _assigns/view_assigns patch will be released (I thought it

# would have been in 3.0.1, but 3.0.1 bypassed this change for a
-
# security fix), this bit ensures that we do the right thing without
-
# knowing anything about the Rails version we are dealing with.
-
#
-
# Once that change _is_ released, this can be changed to something
-
# that checks for the Rails version when the module is being
-
# interpreted, as it was before commit dd0095.
